Debugging Avaya SIP

I have been speaking at the annual IAUG (International Avaya Users Group) conference long before they called themselves the IAUG. In fact, given that my heritage is both Nortel and Avaya, I’ve been a regular at both INNUA (International Nortel Users Association) and InAAU (International Alliance of Avaya Users) get-togethers since the dawn of time […]

Zang From the Inside Out

When I was a kid growing up in the 1960’s, the big question of the day was “Mary Ann or Ginger?”  Being the fairly wholesome, innocent child that I was, my answer was always the same – Mary Ann.  Ginger certainly had her appeal (which grew as I got older), but Mary Ann was the […]

Survivability and Avaya Media Gateways

Writing these technical articles serves two purposes. First, I love having the opportunity to play unified communications professor. I have been in this industry for a long time and I truly enjoy sharing what I’ve learned about telephony, SIP, WebRTC, and VoIP in general. Second, I find that I don’t really understand something until I […]

A Detailed Look at the SIP PRACK Method

As many of my readers know, every few months I teach a two and a half day class on “all things SIP.” My students are exposed to everything from “why SIP” to the nitty-gritty of SIP requests, responses, and call flows. I even speak about some of the more esoteric topics such as To and […]

The Avaya Engagement Call Control Snap-In

Not only do I write for No Jitter, but I am also an avid reader of all its articles. While I enjoy nearly every topic my fellow writers explore, I am especially intrigued by those that address programming and APIs (Application Programming Interfaces). That’s not surprising, though, since most of my professional life was spent […]

An Even Closer Look at Avaya Aura Call Processing

Last week, I walked you through how Avaya implements IMS processing between Session Manager and Communication Manager.   Even though it may have looked fairly complicated and slightly convoluted, I actually did you a favor by greatly simplifying the call flow. The complete call flow is even more involved. I also did myself a favor by […]

Toll-Free Text: Let Your Thumbs do the Talking

Technology is a lot like the music business. You can be on top of the charts one day and completely irrelevant the next. The public is very fickle and you either change with the times or risk falling into the dustbins of yesterday’s news. How many of you have sons or daughters between the ages […]

A Developer’s Introduction to Avaya Engagement Call Control (ECC)

I need to start by telling you that I am a Java programmer. Having experienced quite a few computer languages over the years, I started writing in Java fairly exclusively in the late 1990’s. I love the elegance, power, and flexibility of Java. It ran circles around other object oriented languages such as C++ and […]

An Avaya Aura Session Manager Cookbook

A long time ago, I learned that I don’t fully understand something until I can explain it to someone else. Not only does that require me to translate the gobbledygook in my head into words, but it forces me to completely learn the subject I profess to know. Trust me when I say that neither […]

Converge2015: The Road to SIP

If you are a fan of Tolkien’s “The Lord of the Rings,” you know that Aragorn was described by the words “Not all who wander are lost.”  Now, while that’s perfectly fine for a ranger and the future king of Gondor, it’s not fine for IT departments as they move their communications systems to SIP.  […]
